title: [Medication adherence in asthma therapy--a structured review].
abstract: BACKGROUND
  The adherence level of Asthma therapy is low. We provide a literature overview about the determinants of adherence in asthma therapy, and potential options that lead to an improvement of adherence. We also discuss cost issues of poor adherence.
  
  
  METHODS
  A systematic literature search was conducted and 53 articles were identified.
  
  
  RESULTS
  The most prominent driving factors of adherence are patient beliefs, comorbidities, physician-patient relationship, and medication regimen. The cost effectiveness of adherence improving measures has yet to be shown.
  
  
  CONCLUSIONS
  As asthma control is primarily depended on adherence, cost effective adherence programs need to be developed that respond to patients' individual needs.
